    Hi,

    I started using DWSIM recently to simulate some combustion reactions with heat exchange. I have a conversion reactor burning off methane, hydrogen and carbon monoxide. There is some energy leaving the system which is shown on an energy stream that is connected, head first into the reactor.

    However, I was wondering if I could connect this energy stream tail-first into the reactor, i.e. is it possible for an energy stream "inlet connection" coming out of the reactor and the "outlet connection" going into a heater? I wanted the heat leaving the reactor to heat up some water to simulate reaction with heat exchange.

    Thanks
    Prithvi

    Hi,
    this is right. A solution is already in progress.

    I already prepared a commit to GitHub to solve exactely this problem.
    https://github.com/DanWBR/dwsim6/pull/196
    You will have to wait some days still as i need to update some files first.

      Hey Gregor

      Thanks for the quick reply!

      That's great to hear! Is it possible to incorporate that bit of code into my DWSIM file by any chance? Or would you recommend waiting for an update first?

      Thanks
      Prithvi

    Please wait for the update.

    But you might use a workaround in meantime:
    Use a "Specification Block" to read energy stream of reactor and write it's negative value to energy stream of heater. The heater needs to work in mode "Energy stream"

      Awesome, thanks for the help Gregor! Is there a way to be notified when there is an update available?
